Building a house in winter a problem? Your experiences

That must be it. Bet? And then they start lying and treating the customer as if they were stupid, and the mood is gone. Karsten

Be glad that he doesn't continue at these temperatures, the mortar can't set properly, you don't want any late damage

So our construction started on 30.01.17 with pouring the foundation slab. By the end of March, doors and windows were installed. In between, we had a 3-day construction stop because the thermometer showed below -5°C....

A lot of speculation and generalities. The fact that construction can take place under various climatic conditions is proven worldwide by practice. I would say: - Ask the processing guidelines of the respective manufacturers (of course, you have to know which building materials are being used). - Check the contract for work to see if there is a completion date.

Regarding point 1: I received the datasheet, which states that up to >5°C no additional measures are required.
Regarding point 2: The occupancy date is 10 months after completion of the foundation slab. Bad weather, strikes, etc. would extend the deadline.

Bad weather, strike

However, winter is not bad weather (of course I don't know your contract, but I have seen such formulations before ...).
